- Does your string contain a space in the first N characters? If not, abort.
- Truncate at N+1 characters
- Truncate at last space or in string (use the rindex function)
sub truncate_string {
my($string, $maxlength) = @_;
$string = substr($string, 0, $maxlength+1);
die("Can't truncate, no spaces\n") if(index($string, ' ') == -1);
return substr($string, 0, rindex($string, ' ') - 1);
}
All code is, of course, untested.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
